MEDICINAL PREP AB'ATION.

To all 10.7mm it may concern.

Be it known that I, EUSTACE H. GANE, a citizen of the United States, and a resident of New York city, State of New York, have invented certain new and useful Improvements in Medicinal Pre arations, of which the following is a specifihation.

My invention relates particularly to medical preparations of the class that are especially adapted for external application, and is essentia ly directed to the form in which said preparation may be carried and dispensed.

Certain chemicals such for example, as iodine, have in practice been prepared for external use, by dissolving them in alcohol,

* glycerine or other suitable solvent serving as a vehicle, with or without the addition of potassium iodide or other medicaments, and applied to the skin by means of a camel hair brush, swab of cotton or other suitable material, thus imposing obvious disadvantages in its use upon the user.

The principal ob'ects of my invention are to obviate the disa vantages incident to the handling and applying such chemicals, by

embodying them m-a vehicle of such solidified form as to render them not only convenient to handle but readily applied without mechanical agents.

Other objects of my invention are to provide medicaments such as iodine or other medical agents in solidified stick or pencil form, whereby they may be locally applied without posslble spreadin and whereby remote and otherwise di cultly accessible parts may be readily treated.

Specifically stated the form of my invention as hereinafter described comprises a medicament such as iodine combined with a solvent such as alcohol, which may be solidified by the addition of a sodium salt of one or more of the higher fatty acids.

My invention also includes all of the various novel features of arrangement and procedure as hereinafter more definitely described.

My invention further comprehends the method of producing the solldified medicated sticks or pencils as herein set forth.

Specification of Letters latent.

Application illed November-l, 1917. Serial Io. 199,824.

Patented 'Feb. 7, 1922.

.In order to produce such a composition as contemplated, I repare a solution of iodine in alcohol and dissolve in this solution about five per cent of stearic acid by the aid of a water bath, to this I add sufiicient sodium hydrate to exactly neutralize the stearic acid present, about i of one per cent is usually sufficient. The solution is then heated to boiling and poured into molds of convenient size and form. Upon cooling the solution becomes solid and the solidified preparation, prepared in pencil form or other convenient shape, may be conveniently rubbed or applied on the skin to produce all the effects heretofore obtained by the application of tincture of iodine, without the undesirable and disagreeable features incident to the application of such tincture.

It may be here noted that although I have referred specifically to iodine, other medical agents are equally susceptible of aplplication in the same manner as the i0 herein referred to, and therefore I do not desire to limit my invention to the details precisely as herein set forth, as it is obvious that various modifications may be made without departing from the spirit of my invention as defined in the appended claim.

Having thus described my invention, I claim An iodine pencil in form for convenient handling in making restricted local exterior iodine applications without spreading, said ncil composed of a solidified vehicle carrymg a relatively large proportion of tincture of iodine of the necessary strength for local application as a medicament, said vehicle being capable of wearing away on the surface of the body to which it is a )plied and thus depositing the iodine carried by the portion of the vehicle removed from the pencil.

In witness whereof, I have hereunto set my7hand this 27th day of October, A. D., 191

EUSTACE H. GANE.
